Referring to the drawings wherein like numerals. designate like parts,it can be seen thatnumeral 5 represents a base which has the upright 6thereon. This uprightfi is provided with a shelf 7 and an intermediateportion thereof for supporting the electric motor 8 and with a secondshelf 9.1ocated at itsupper end for supporting the (is electric motor10. Y e

Numeral 11 represents a bearing supported upon thebase 5 and throughthis is journalled the shaft 12. At one end of this shaft 12 the sameextends into. the tubular extension 13 which forms a shaft carrying theelongated pulley drum 14. Pulleys 15, 16 and 1'7 areprovided on thisshaft 13. At the intermediate portion of the shaft 12 is a large pulley18,}while at the opposite end of the shaft 12 from the shaft 13 is auniversal unit, consisting of the frusto-cone 19 disposed againstthecollar 20 at one end (the smallest end) rest-v ing on the ballbearing mountZl at its opposite end. This ball bearing mount 211sinterposed betweenthe abutting end ofthe cone 19 and the s1eeve22 whichsleeve is provided withthe shoulder 23. thereon disposed in a directionintersecting. the longitudinal axis of theuniversal unit oblique- 1y'forthe purpose of feeding the material which is supportedby the cone;19 and partly by the cylinder 2e to a position-:under the rotary knife25; driven by the aforementioned motor 8. The sleeve 22 is providedwithla slot 26 extending circumferentially for about half the distancearound the blade toreceive the flexible needle, brass or like materialdesignated by numerals 2"I,so that the same will project to swing adistance beyond the periphery of the sleeve 22 when extended in theposition shown in-Figure 3.; p 1,

The needles 27 project from the glass disk 28 through a .leather jacket29 surrounding the periphery o f the disk 28, and obviously can easilypass within the space between the sleeve and the jacket 29 asshown'onthe right in Figure 13. A belt 30 is employed to feed the clothinto the blade 25. 'This belt 30 isdriven by the pulley 31 and operateslooselyoverthe stationary cylinder 19. This cylinder. forms a coverholding the fiber shoe which the b1ade 25 cutsinto; The sleeve 19 isoperated by the shaft 12, the. cloth being pushed up on the cylinderbyhand from the cylinder 24, until it comes in contact with the belt 30.The belt then feeds thecloth into the blade 25, whereupon the stripwhich has been cut is pulled away from the blade 25 by the needles 2'?-in such a way that the cloth strip can be pickedup by hand and the windstarted around the reel 50. (While this hand operation is beingaccomplished, the machine is momentarily stopped.) When the clothstriphas been placed around the reel 59, the ma chine is put into gearand the remainder of the cloth is cut and wound up on the spool.

The aforementioned cylinder 24 is hollow to receive the collar 20 of theuniversal unit and the cylinder 24 is supported upon the head 32 carriedby the rod 33 which projects from the bearing 34. The bearing 34 isstationary and forms a support that is bolted to the machine. The samesupports the cylinder 24, the latter being the member over which thecloth is pulled before being cut. At the inner end of the cylinder 24are inwardly projecting lugs 3535 which are engaged by the catches 36 onthe collar 20 to prevent displacement of the cylinder 24 from the collarand from associationwith the -aforemen-, tioned universal unit.

The shaft 37 which supports not only the pulley 31, but the pulley 38also, is in turn supported by the standards 39 and 40, suitably securedto the aforementioned base 5. Crossed belts 41 are trained over thepulleys l7 and 38 as shown in Figure 3, while the small pulley 42 on theshaft 43 has a belt 44 trained thereover and. over the large pulley 18,whereby the shaft 12 is driven bythe shaft 43, while the aforementionedshaft 37 is driven by the shaft 12. The shaft 43 is driven by a belt 45trained over the pulley 46 on the armature shaft of the motor 10 andover the large pulley wheel 47 on the aforementioned shaft 43. Thepulleys 47 and 44 with the shaft 43 are supported by the standard 48. I

A reel 50 is carried by the shaft 51, and one end portion of said shaftis pointed as at 52, to facilitate engagement of the reel on the shaft51, while numeral 52 represents a'small pulley wheel. Numeral 53 (seeFig. 6) represents a collar to which the L-shaped part 54 is secured.This arm 54 at its outer laterally disposed end is provided with a head55 alined with one of the ends of the T-shapedmember 56. The other endof the T- shaped member is alined with the head 57 of the outer end ofthe L-shaped arm 58 which is secured to the end of the shaft 51 oppositeto the end supporting the reel 50. This winding mechanism is mounted bya suitable bracket to the base.

Adjacent to the shaft 51 are the bearings 59-59 for journallyreceivingthe internally threaded sleeve 60 on which the pulleys 61 and62 are freely rotatable, each being provided at its inner side with apair of diametrically oppositely located teeth 63; r

Mountable on the sleeve 60 and between the pulleys 61 and 62 and splinedto the sleeve 60 as at 64, is a spool 65 having end circumferentialflanges 66 and 67. The outer side of each of these flanges is providedwith a pair of diametrically oppositely located teeth 68. .As is clearlyshown in Figure 6, the inner end of the T-shaped member 56 engagesbetween the flanges 66 and 67 as at 69, (see Fig. 6) while guides 70 areprovidedfor the two end'portions of the two members located outwardly ofthe spool 65.]Guides 70 obviously maintain the outer ends of theT-shaped member .alined with'the arms 54 and 58. An elongated shaft 71is provided with threads 72 threadedly disposed through the sleeve 60and this shaft 71 is provided with a longitudinally extending slot 73therein into which engages the key 74 on the bear ing 59, thuspreventing the shaft 71 from rotating. The ends of the shaft 71 aresecured to the arm 54 and the arm 58.

An endless belt 75 is trained over the pulleys 62 and 16 (see Figure 1)while a crossed belt 76 is trained over the aforementioned pulleys 61and 15 (see Figure l).

Trained over the drum 14 and the small pulley 52 on the shaft 51 is abelt 77, the belt 77 obviously being able to travel along the drum 14 asthe shaft 51 and its pulley 52 travels back and forth. The drum 14, belt77 and pulley 52 afford drive means for the reel 50. The cloth to be cutis in tubular form. This tube of course is pushed up on the cylinder 24by hand over the cone 19 until it comes in contact with the belt 30. Ascan be seen by the drawings (Fig. 3), this belt 30 is pulled by thepulley 31, the pulley 31 being driven by the shaft 37 which in turn isdriven by the pulley 38. As is seen in Fig. 3, this shaft 37 is placedat an angle across the machine which angle causes the belt 30 to runacross the sleeve 23 at the same angle so that when the belt 30 feedsthe cloth into the blade 25, it starts at an angle causing. the cloth tobe cut in ribbon-like strips. When the machine is in gear and cylinder24 is pushed in contact with the cone 19, the collar 20 is caused toturn with the sleeve by means of the catches 36. All the while themachine is operating and cutting the cloth, the cylinder 24 is turningwith the cloth thereon at the same speed as the rest of the machine. Theneedles 27 pull the cut ribbon-like strip away from the blade 25 so thatit can be picked up by hand and started around the spool 50.

It can now be seen, that by moving the cylinder 24 apart from the collar20, the tubular textile material can be placed thereon after thecylinder 24 has been attached to the collar 20. The materials now inposition and by engaging the same against the inner side of the belt 30and then starting the two motors, the material, with the assistance ofthe belt 30 and the needles 27 will be fed under the knife 25 and byfastening the starting end of the material to the reel 50, the cutmaterial can be uniformly wound on the reel, by the operation of thefeeding mechanism hereinbefore clearly described. The width of the stockis three-fourths of an inch more or less.

It will be observed that when the reel has reached one extreme oftravel, the head 55 or head 57 will engage one outer end of the T-shaped member 56 and this will obviously grip the spool 65, (see Figure4) so that its teeth 68 will disengage from the teeth'of one pulley 61or 62; to engage with the teeth of the other pulley so that the drivewill be changed from the parallel belt 75 to the crossed belt 76 thusreversing the drive motion between the shaft 13 and internally threadedsleeve 60, which feeds shaft 71 longitudinally. In regard to the beltdrives, it can be seen that the motor 10 by way of the pulleys 46 and 47and belt 45 drive the pulley 42. The pulley 18 on the shaft 12 has theaforementioned pulley 42 and the belt 44 trained over the same. On theshaft and driven by the pulley 18 is the pulley 17 and this drives thepulley 38 by way of the belt 41. Thus power is supplied to the shaft 37which also carries the pulley 31. Trained over the pulley 31 and sleeve22 is the belt 30. In this manner, power is supplied to operate the cone19 of the fabric feeder. As is clearly shown in Fig. 1, a belt 75 istrained over the pulleys -l6'and 62 and has its flights parallel, whiletrained over the pulleys 61 and 15 is a belt 76 whose flights arecrossed to secure reverse motion. v

While the foregoingspecification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, size,and materials may be resorted to without departing from the spirit orscope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is: i

1. In a textile cutting machine, a material supporting cylinder, a belt,a rotary knife adjacent the cylinder and belt between which and thecylinder textile material engages to be fed from the cylinder to aposition where the same cylinder, and a belt for feeding the materialfrom the cylinder to a position where the same can be cut by the knife,and a reel on to which the cut material can be wound, and. means forreciprocating the reel whereby the material can be uniformly woundthereon, a motor, said motor being adapted to drive both the reel andthe belt.

4. In a textile cutting machine, a material supporting cylinder, arotary knife adjacent the cylinder, and a belt for feeding the materialfrom the cylinder to a position where the same can be cut by the knife,the cylinder being provided with a circumferentially extending slottherein, a shaft passing into the cylinder, 9/ disk on the lastmentioned shaft, and flexible teeth on the periphery of the diskprojectible through the slot for engaging the material on the cylinderto feed the same to the knife.
